Now form a sua = d3 ds - ap - as - sig dz ds = Sas. as = av + vav as = Dt Dv of S
Consideoring force, strady flow and negeting body steady flow of av =0 for non viscon body fore = Ig EO. fluid Inviscid - 2p S (v av ) = as as Pressure gradient = velocity Gradient Pressure reduces = Velocity Increases
